Yes they can very well do as EM64T means Extended Memory 64-bit Technology which itself clarifies it
The Xeon with EM64T and Pentium 4 with EM64T processors
Only if the processor has special 64-bit extensions, known as AMD64 or EM64T. Certain Pentium 4 processors, all Core 2 processors, and all AMD Athlon 64 processors have these extensions, and can thus run 64-bit operating systems and programs.
All Cedar Mill and Prescott 2M processors (those in the 6xx line) support EM64T. Prescott processors with a model number of 517, 524, 531, 541, 551, 561, or 571 also support EM64T.
Xeon (according to Wikipedia)
The instruction set is usually called IA-64. This is not to be confused with EM64T, a 64-bit instruction set used in mainstream desktop processors. The answer your looking for is (EPIC)Explicitly Parallel Instruction Computing Chicagocubano strikes again
You can do this by identifying your processor brand and model. Many tools that can do this, such as CPU-Z, will also list the features of the processor for you, such as EM64T (on Intel processors) or x86-64 (on AMD processors). Note that it is quite possible to run a 32-bit operating system and programs on a 64-bit capable processor, so just because you are running one doesn't mean you can't run a 64-bit one.

Yes, if installed on an AMD64 / EM64T compatible processor, Windows 2000 will not be able to take advantage of the additional addressing capabilities, however. There is also a 64-bit version of Windows 2000 available only for Itanium chips.
Yes. EM64T refers to the processor supporting 64-bit extensions. It is analogous to (and mostly compatible with) the AMD64 instruction set.
It virtually completely depends on you. I prefer Windows XP over Vista, but generally Vista computers require more memory, RAM, higher processors, etc. The following are the requirements for AutoCAD: == The system requirements for 32-bit AutoCAD: * Intel® Pentium® 4 processor, 2.2 GHz Recommended * Microsoft® Windows Vista™, Windows® XP Home and Professional (SP2), Windows® 2000 (SP4) * 512 MB RAM * 750 MB free disk space for installation * 1024x768 VGA with True Color * Microsoft® Internet Explorer® 6.0 (SP1 or higher) Available on CD (Worldwide) and DVD (select countries and languages) == * Windows XP Professional x64 Edition and Windows Vista 64-bit * AMD64 or Intel EM64T processor * 1GB RAM, 2GB for Windows Vista 64-bit * 750 MB free disk space for installation AutoCAD 64-bit cannot be installed on a 32-bit Windows Operating System. == * Intel® 3.0 GHz or greater * 2 GB RAM or greater * 2 GB free hard disk available not including installation * 1280 x 1024 32-bit color video display adapter (True Color) 128 MB or greater, OpenGL®, or Direct3D® capable workstation class graphics card. * For Windows Vista, a Direct3D capable workstation class graphics card with 128 MB or greater is required.

With Vista, you will find that "handle" depends more on the available memory than the processor. The Core 2 Duo supports EM64T, so it is physically capable of running Vista.
